The manufacturing plan and the material selection for a digitally controlled L-band step attenuator

Abstract

This article investigates the processor and manufacturing techniques of a digitally controlled L-band step attenuator, which accrues in the endeavor to implement required dimensional and geometric tolerances and further material selection. On the basis of the digitally-controlled step attenuator, the plan of simulation of the L-band step attenuator is proposed, and precise information is used to implement a detailed material selection process, consisting of several techniques such as literature review, SolidWorks modeling, and expert interviews to assign more preference to design reliability, robustness, and practicality of the prototype. The module of material selection of the SMA connector requires high consideration of cost and performance for corrosion resistance. Such components require perfect alignment with some components with appropriate surfaces and dimensions. It is proved in this research that precise design and material selection can significantly improve the manufacturing efficiency and product stability of the array. L-band step attenuators have some demanding manufacturability requirements. The details of the manufacturing technique and the logic employed to reach these demands contain vital information.
